Key Parameters

Substitute Part Grouping Explanation

Equivalent and substitute parts for the R574803625 are determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Frequency Range: 0Hz ~ 40GHz (exact match required)
• Impedance: 50Ohm (exact match required)
• Isolation: 50dB minimum (exact match required)
• Insertion Loss: 1.1dB maximum (exact match required)
• Supply Voltage: 24V ~ 30V (exact match required)
• Operating Temperature: -40°C ~ 85°C (exact match required)
• Package Type: Module (exact match required)
• RF Type: General Purpose (exact match required)
• Manufacturer: Radiall USA, Inc. (exact match required)

Secondary Consideration:

• Circuit Configuration (SPnT): Substitutes may vary in throw count (SP3T, SP4T, SP6T) provided all primary electrical parameters remain identical. The selection of throw count depends on application-specific circuit requirements.

All substitute parts listed meet these criteria and are manufactured by Radiall USA, Inc. with Active product status and ROHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

R573883600 (SP6T Configuration) This part is the direct functional equivalent to the R574803625, sharing identical circuit configuration (SP6T), electrical parameters, and compliance certifications. Both parts are ROHS3 compliant and Active in product status. Selection of R573883600 is appropriate when the primary part is unavailable or when inventory optimization is required.

R573883400 (SP4T Configuration) This part meets all electrical and mechanical parameter requirements but provides SP4T (four-throw) functionality instead of SP6T (six-throw). Selection is appropriate for applications requiring four switch positions rather than six, provided circuit design accommodates the reduced throw count.

R573803320 (SP3T Configuration) This part meets all electrical and mechanical parameter requirements but provides SP3T (three-throw) functionality instead of SP6T (six-throw). Selection is appropriate for applications requiring three switch positions rather than six, provided circuit design accommodates the reduced throw count. RoHS status is not specified for this part.

All substitute parts are manufactured by Radiall USA, Inc. and maintain Active product status with identical frequency range, impedance, isolation, insertion loss, supply voltage, and operating temperature specifications.

Frequently Asked Questions (FAQ)

Q: Can R573883600 be used as a direct replacement for R574803625? A: Yes. Both parts are SP6T RF switches with identical electrical parameters (0Hz ~ 40GHz frequency range, 50Ohm impedance, 50dB isolation, 1.1dB insertion loss, 24V ~ 30V supply voltage, -40°C ~ 85°C operating temperature), Module package type, and ROHS3 compliance. They are functionally equivalent.

Q: What is the difference between the SP3T, SP4T, and SP6T configurations? A: The designations refer to switch throw count. SP3T provides three selectable output positions, SP4T provides four positions, and SP6T provides six positions. All three configurations share identical electrical performance parameters when manufactured by Radiall USA, Inc. in this product line. Selection depends on the number of switch positions required by the application circuit.

Q: Are all substitute parts ROHS3 compliant? A: R573883600 and R573883400 are explicitly ROHS3 compliant. R573803320 does not specify RoHS status in the provided data. Compliance verification is required before selection if ROHS3 certification is a design requirement.

Q: Can I use an SP4T switch in a circuit designed for SP6T? A: Circuit compatibility depends on application requirements. If the circuit design requires six switch positions, an SP4T switch cannot provide the necessary functionality. If the circuit can operate with four positions, R573883400 is electrically compatible. Circuit redesign may be necessary.

Q: What is the operating frequency range for all substitute parts? A: All substitute parts operate across 0Hz to 40GHz with 50Ohm impedance and are tested at 40GHz. This frequency range is identical across R574803625, R573883600, R573883400, and R573803320.

Q: Are there inventory differences between the main part and substitutes? A: Yes. R574803625 has 977 pieces in stock, R573883600 has 957 pieces, R573883400 has 1044 pieces, and R573803320 has 734 pieces. Inventory levels may influence part selection for procurement planning.

Q: What supply voltage is required for all these RF switches? A: All parts require 24V to 30V supply voltage. Power supply design must accommodate this voltage range for any of these components.
